OsOSCA2.4 regulates post-Golgi trafficking of storage proteins by modulating Ca2+ homeostasis in rice endosperm

Abstract. Seed storage proteins (SSPs), which accumulate specifically during seed development, constitute a major source of plant-derived protein in the hu

⚡ SPECIAL ISSUE REVIEW ⚡ A crosstalk exists between reactive oxygen species (ROS) and calcium (Ca2+) signaling. In this review, Jiménez et al. highlight how thioredoxins mediate redox regulation of Ca2+ transporters, sensors, and effectors. 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

🌱💧 Can we improve drought tolerance without relying on ABA? Our latest study identifies two small molecules that inhibit plasma membrane K⁺ channels, triggering stomatal closure, Ca²⁺ elevation, and enhanced drought resistance through an ABA-independent pathway. 🔗 www.nature.com/articles/s41...

Synthetic ion channel inhibitors enhance plant drought tolerance - Nature Communications

Drought stress significantly threatens global food security by limiting plant growth. Here, authors demonstrate that chemical inhibition of potassium channels induces stomatal closure and enhances dro...

Excited to share our new work on pollen tube growth in Arabidopsis thaliana! 🌱 We show that vacuolar and ER Ca²⁺-ATPases are key regulators of calcium dynamics during pollen tube growth. A great collaboration with the Muschietti and Estevez labs 🤝 academic.oup.com/plphys/artic...

Vacuolar and ER-Ca2+-ATPases regulate calcium dynamics during pollen tube growth in Arabidopsis thaliana

Proper pollen tube growth in Arabidopsis thaliana requires maintenance of the cytoplasmic Ca2+ gradient by vacuolar and ER Ca2+-ATPases.
